Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a wax for joining ceramics to ceramics, ceramics to graphite, ceramics to metal, graphite to metal, and metal to metal.

A brazing filler metal made of a eutectic composition of these and Ni and Cu, which form alloys with relatively low melting points, is inserted between the ceramic nox and the metal, and brazed in a vacuum or inert gas. This is the method of attaching.

張率が高い、ろう付継手強度が低い等の問題があった。Incidentally, in recent years, there has been a strong demand for brazing filler metals with creep resistance, corrosion resistance, oxidation resistance, etc., for strength at high temperatures, especially for materials used for joining parts that are exposed to high temperatures for long periods, including for the space shuttle. However, the brazing filler metal used in the active metal method has problems such as softening of the metal base material, high coefficient of thermal expansion, and low brazed joint strength.

ある。In the brazing filler metal of the present invention, the reason why PT is set to 30 to 92-t% is that if it is less than 30-t%, the corrosion resistance as a brazing filler metal is poor.
This is because the oxidation resistance deteriorates, and if it exceeds 92 wt%, the mechanical strength decreases and the function of the brazed joint deteriorates.

-, Y SCr 1MO1 The reason why at least one of Mn, B, and WSRe is set at 0.5 to 10-t% is to increase the strength of the brazed joint, and if it is less than 0.5 wt%, it may cause wetting to ceramics and graphite. If it exceeds 10-t%, the melting point of the solder increases, and at least one of Ti, Zr, Hf-, etc., remains in the solder. The amount of brittle intermetallic compounds increases and the strength of the brazed joint deteriorates.

ものである。The reason why at least one of Au, Ag, Pd, Cu, and Ni was set at 0.5 to 69.5 wt% is to lower the melting point of the brazing filler metal as much as possible, improve wettability, and increase the strength of the brazed joint. If it is less than 0.5 wt%, there is no effect, and if it exceeds 69.5 wt%, the plastic workability decreases.

のである。The brazing filler metals of Examples 1 to 5 having the compositions shown in Table 1 below were melted in a high-frequency vacuum furnace, cast into iron molds, solidified, and rolled to form plates of 0.1 mm thickness. The brazing filler metal of Conventional No. 1.2 was also manufactured in exactly the same manner as in the example.

果を得た。However, each of the brazing materials of Examples 1 to 5 and Conventional Examples 1 and 2 was cut into a size approximately equal to the size for brazing, and used to melt alumina and alumina, and alumina and graphite in a vacuum (1
0-3T o r r ) to create a joint. The brazed joint sample obtained in this way was heated to high temperature (in the atmosphere).
The high temperature strength after holding at 1000° C. for 24 hours was measured using a 4-point bending strength tester, and the results shown in Table 2 below were obtained.

従来例１．２のろう材に比し、ろう付温度が低く、且つ
ろう付強度が高いことが判る。As is clear from Table 2 above, the brazing materials of Examples 1 to 5 were:
It can be seen that the brazing temperature is lower and the brazing strength is higher than the brazing metal of Conventional Example 1.2.

とのできる画期的なものと言える。(Effects of the Invention) As described above, the brazing filler metal of the present invention makes it possible to obtain brazed joints with high brazing strength even when exposed to high temperatures for long periods of time. The target strength can be increased. Furthermore, the brazing material of the present invention is stable with very little oxidation even when exposed to high temperatures for a long period of time, so it has high reliability. Furthermore, since the brazing filler metal of the present invention has a low coefficient of thermal expansion, it has the effect of relieving thermal stress with ceramic nox, so it can be used as a high-grade heat-resistant brazing filler metal that requires reliability, compared to conventional brazing filler metals. It can be said to be an epoch-making product that can be replaced.
